The Emerald Necklace Conservancy, the color company Pantone, and the Revere Hotel teamed up on Thursday night to celebrate all things green and sparkling. The Night of Beauty & Elegance marked the 15th anniversary of the Conservancy and highlighted Pantone’s “color of the year,” which just happens to be emerald. Not surprisingly, the event was at Emerald, the hotel’s “Wizard of Oz”-inspired lounge. The guest list included HGTV’s Taniya Nayak, who helped design the party space; Long’s Jewelers CEO Bob Rottenberg, John Lineham, CEO of the Franklin Park Zoo; Pantone marketing manager Molly Walsh; and florist John LaRoche of blueGuava.
